Begonia plant named ‘BKPBEBVDS’

ABSTRACT

A new and distinct cultivar of Begonia plant named ‘BKPBEBVDS’, characterized by its broadly outwardly spreading to trailing plant habit; freely branching habit; dark green-colored leaves; freely flowering habit; and reddish orange-colored flowers.

Botanical designation: Begonia boliviensis.

Cultivar denomination: ‘BKPBEBVDS’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia boliviensis and hereinafter referred to by the name ‘BKPBEBVDS’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Maasdijk, The Netherlands. The objective of the breeding program was to develop new freely branching and freely flowering Begonia plants with attractive flowers and good garden performance.

The new Begonia plant originated from a cross-pollination made by the Inventor in September, 2014 of a proprietary selection of Begonia boliviensis identified as code number 11-0026-02, not patented, as the female, or seed, parent with a proprietary selection of Begonia boliviensis identified as code number 14-0069-02, not patented, as the male, or pollen, parent. The new Begonia plant was discovered and selected by the Inventor as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Maasdijk, The Netherlands in May, 2015.

Asexual reproduction of the new Begonia plant by vegetative tip cuttings in a controlled greenhouse environment in Maasdijk, The Netherlands since December, 2015 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BKPBEBVDS’. These characteristics in combination distinguish ‘BKPBEBVDS’ as a new and distinct Begonia plant:

-   -   1. Broadly outwardly spreading to trailing plant habit.     -   2. Freely branching habit.     -   3. Dark green-colored leaves.     -   4. Freely flowering habit.     -   5. Reddish orange-colored flowers.

Plants of the new Begonia can be compared to plants of the female parent selection. Plants of the new Begonia differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Begonia are more compact than plants of the         female parent selection.     -   2. Plants of the new Begonia have reddish orange-colored flowers         whereas plants of the female parent selection have         orange-colored flowers.

Plants of the new Begonia can be compared to plants of the male parent selection. Plants of the new Begonia differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Begonia are more compact than plants of the         male parent selection.     -   2. Plants of the new Begonia have reddish orange-colored flowers         whereas plants of the male parent selection have dark         pink-colored flowers.

Plants of the new Begonia can be compared to plants of the Begonia pendula X Begonia boliviensis ‘Encanto Orange’, disclosed in U.S. Plant Pat. No. 20,898. In side-by-side comparisons, plants of the new Begonia differ from plants of ‘Encanto Orange’ in the following characteristics:

-   -   1. Plants of the new Begonia are more compact than plants of         ‘Encanto Orange’.     -   2. Plants of the new Begonia have reddish orange-colored flowers         whereas plants of ‘Encanto Orange’ have bright orange-colored         flowers.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying colored photographs illustrate the overall appearance of the new Begonia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Begonia plant.

The photograph on the first sheet (FIG. 1 of 2) is a side perspective view of a typical flowering plant of ‘BKPBEBVDS’ grown in a container.

The photograph on the second sheet (FIG. 2 of 2) are close-up views of upper and lower surfaces of typical leaves and flowers of ‘BKPBEBVDS’.

DETAILED BOTANICAL DESCRIPTION

Plants used for the aforementioned photographs and following observations and measurements were grown in 10.5-cm containers during the summer in a glass-covered greenhouse in Maasdijk, The Netherlands. During the production of the plants, day temperatures ranged from 19° to 20° C., night temperatures ranged from 18° C. to 19° C. and light levels averaged 6,000 foot-candles. Plants were eleven weeks old when the photographs and the description were taken. In the following description, color references are made to The Royal Horticultural Society Colour Chart, 2015 Edition, except where general terms of ordinary dictionary significance are used.
